Getting Help

The Galaxy S4 comes with a very nice help application. Unfortunately, it is not immediately accessible from the home screen. Instead, you need to go to the Apps view, and open it from there.

On some devices, such as the Galaxy S4, you can switch from Standard Mode to Easy Mode. Go to:

Settings | My Device | Home Screen Mode

Choose Easy Mode or Standard Mode

Here are some examples of Easy Mode. All the other screen shots on this page unless explicitly stated otherwise, are of standard mode.

Here is the Home Screen in Easy Mode. Notice that there are now just two panes in addition to the Home Screen. See the little icons at the very bottom of the screen? They show icons for the home page, and the two panes.

Galaxy S4 Sensors

Proximity Sensor

Ambient light sensor: This is the tool used to dim or brighten the screen according to the amount of light around you. In other words, if the room is dark, the screen dims, if it is bright, then the screen gets bright.

Accelerometer: It tells how fast the thing is moving, but also the phone's orientation

Magnetometer: Turns your phone into a compass, and aids the accelerometer.

Gyroscope: Measures your position in space and works with the accelerometer

Weather related: Humidity, pressure, temperature

Infared (RGB Light) Sensors: Used to pick up on your gestures so you can flip through pictures or scroll through text without touching the screen
